摘要： The instant invention is directed to an article irradiation facility that comprises, within a cell, an accelerator for generating a radiation beam and a beam pass conveyor. In order to better control the dose delivered to articles treated at the facility, the current of the radiation beam is slaved to the speed of the beam pass conveyor. The actual (versus requested) speed of the beam pass conveyor is continuously monitored using a variable frequency drive. The drive infers the speed of the beam pass conveyor from changes in the induction, resistance, flux current and/or inertia off the motor for the beam pass conveyor. The drive is positioned outside the cell and eliminates the need for speed sensors within the cell that are susceptible to radiation damage.

摘要： The present invention is related to a process for irradiation of a product pallet having four vertical faces by a photon beam such as an X-ray beam, a gamma source or similar, consisting in an irradiation procedure comprising the following steps: introducing the product pallet into an irradiation zone according to a horizontal translation movement, submitting said product pallet to said photon beam, the source of which having a vertical movement, the horizontal translation movement of the product pallet and the vertical movement of the beam resulting in the irradiation of a vertical face of said product pallet, moving out said product pallet from the irradiation zone. giving a rotation of substantially 90° to said product pallet using rotation means, repeating said irradiation process until at least the four vertical faces of said product pallet have been irradiated. The present invention is also related to an apparatus and to the use of said process or said apparatus for irradiating a product arranged on a pallet, said product being either of low or of high density.
